OILING DEVICE.

Specification of Letters Patent.

Patented June 2, 1914.

Application filed July 31, 1913. Serial No. 782,837.

To all whom it may concern:

Be it known that I, MICHAEL PAGE, a citizen of the United States,residing at Schuylkill Haven, in the county of Schuylkill, State ofPennsylvania, have invented certain new and useful Improvements inOiling Devices; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in oiling devicesand has particular reference" to gravity fed oiling devices.

The object of the invention resides in the provision of means whereby apitman may be longitudinally bored and said bore utilized as an oilreservoir for oiling the crank shaft and the invention furthercontemplates the provision of means whereby the flow of oil from thesaid reservoir may be regulated at will.

A further object of the invention resides in the provision of such adevice which is so simply designed that it may be put in operation at acomparatively low cost.

With these and other objects in view the invention resides in the novelcombination, formation and arrangement of parts to be more fullyhereinafter described and illus trated in the accompanying drawings andparticularly pointed out in the claims hereto appended.

Reference is had to the accompanying drawings wherein similar charactersof reference designate corresponding parts throughout the several views,and in which:

Figure 1 is a top plan view of the device, Fig. 2 is a side elevationalview thereof, 3 is a horizontal sectional view therethrough and Fig. 4is a sectional View on the line t l of Fig. 1.

Referring now more particularly to the drawings, wherein is shown thepreferred embodiment of the invention 5 designates the crank shaft whichis connected to the pitman 7. Surrounding the olfset portion 8 of thecrank shaft is a bearing 9 and a U shaped member 10 connects thebearings and the adjacent end of the pit-man by means of the usual wedgekey and bolts 11 passed therethrough, the end of the pitman seating in asocket 12 in the bearing.

The pitman is provided with a bore 13 which extends from its endadjacent the bearing to a point adjacent its other end and from saidlast-named end a smaller bore 14: extends laterally to the surface ofthe pitman whereby the main bore may be filled with oil, a suitable plug15 being provided for closing the bore 1 1. Extending to the main boreat a point inwardly of and adjacent the outermost securing bolt 11 is asmall bore 16 wherein is seated a lateral extension 17 of a valve casing18. The bushing is provided with a bore 19 which extends parallel to thepitman and from its surface adjacent the valve casing to a pointadjacent and spaced from the offset portion of the crank shaft. A bore20 is provided transversely in the boxing and communicating with thebore 19, said bore 20 terminating adjacent the central axis of thepitman and communicating with a bore 21, opening upon the innerperiphery of the bearing, the outer end of the bore 20 being closed by aplug 2- A pipe 23 extends from the valve casing to the outer end of thebore 19.

From the foregoing it is observed that the oil passes from the mainreservoir or bore through the bore 16 into the valve casing and fromthence through the pipe 23 and bore 19 to the bore 20 from whence itpasses through the short bore 21 to the in nor periphery of the bushingto properly lubricate the same.

To regulate the flow of oil, a valve stem 24L is disposed in the valvecasing and has threaded engagement therewith the inner end of the valvestem carrying a head 25 whereby rotation of the valve stem actuates thehead to regulate the supply of oil. The valve stem extends outwardly ofthe casing and is provided with a wheel 25 for rotating the same. Tolock the stem against undesired rotation the periphery of the wheel isprovided with a plurality of ratchet teeth and a spring pawl 26 isprovided normally engaging the teeth. This pawl is held in place byforming one end thereof with a bore 27 through which is passed theextension 17 of the valve casing.

To prevent leakage of oil from the main bore at the bearing end of thepitman, a plug is disposed in this end and is securely held in place bythe bolts 11 and by the inner end of the extension of the valve casing,which is disposed in the bore, as shown.

It is thus observed that a very simple arrangement has been providedwhereby a constant flow of oil may be provided for lubricating the crankshaft. It is understood that the application of this device is notlimited to a pitman and as it may be embodied in any similar structure.

It will be understood that various minor changes and modificationswithin the scope of the appended claims may be made without departing inany manner from the spirit of the invention.

that is claimed is:

1. An oiling device comprising the combination with a connecting rod anda shaft bearing at one end thereof, of the rod being provided with alongitudinal bore forming an oil reservoir and an outlet bore adjacentthe bearing, a valve casing having an extension seated in the last bore,a stem and head in the casing and the bearing being suitably bored andthe valve casing communicating therewith whereby oil is supplied to theinner periphery of the bearing.

2. An oiling device comprising the combination with a connecting rod anda shaft bearing at one end thereof, of the rod being provided with alongitudinal bore forming an oil reservoir and an outlet bore adjacentthe bearing, a valve casing having an extension seated in the last bore,a stem and head in the casing and the bearing being suitably bored andthe valve casing conimunicating therewith whereby oil is supplied to theinner periphery of the bearing.

3. An oiling device comprising the combination with a reservoir and afeed pipe, of a. valve casing, an extension on said casing communicatingwith the reservoir, a valve stem threaded in the casing, ahead on thestem, the outer end of the stem being provided with a wheel havingratchet teeth on its periphery and a spring pawl bored at its lower endto receive the extension whereby it is held by the extension and thereservoir with its upper end resiliently engaging the teeth.

In testimony whereof, I afiiX my signature, in the presence of twowitnesses.
